XWD型臥式靜電除塵器是眾多除塵器當中的一種，臥式靜電除塵器是以靜電凈化法來收捕廢氣中的粉塵的設備，其主要是讓含塵氣體進人氣刺叭時，含塵氣體受到氣流分布板以及折流板的調整后，使氣流能較均勻地進人電場。

臥式靜電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器是(shi)以(yi)靜電(dian)(dian)(dian)(dian)(dian)(dian)凈(jing)化法來(lai)收(shou)捕廢氣(qi)(qi)中(zhong)的(de)粉塵(chen)(chen)(chen)，它的(de)凈(jing)化工(gong)作(zuo)上要(yao)是(shi)依靠電(dian)(dian)(dian)(dian)(dian)(dian)暈極和(he)沉淀兩(liang)個系(xi)統(tong)來(lai)完成(cheng)的(de)，當含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)(ti)進(jin)(jin)人(ren)(ren)氣(qi)(qi)刺叭時，含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)(ti)受到氣(qi)(qi)流(liu)分布板以(yi)及折流(liu)板的(de)調整后，使氣(qi)(qi)流(liu)能較均勻地進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)橫斷面擴大(da)的(de)作(zuo)用(yong)下，氣(qi)(qi)流(liu)速度(du)迅速降低，其(qi)中(zhong)有些較重的(de)塵(chen)(chen)(chen)粒便失去(qu)速度(du)而沉降下來(lai)。進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)(dian)暈極通(tong)人(ren)(ren)高(gao)壓(ya)直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)暈極附近(jin)產生電(dian)(dian)(dian)(dian)(dian)(dian)暈現象(xiang)，使氣(qi)(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)(dian)離后的(de)氣(qi)(qi)體(ti)(ti)(ti)中(zhong)存(cun)在(zai)大(da)量(liang)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)子和(he)離子，這些電(dian)(dian)(dian)(dian)(dian)(dian)子和(he)離子與進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)粉塵(chen)(chen)(chen)結(jie)合起來(lai)，使塵(chen)(chen)(chen)粒帶電(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)作(zuo)用(yong)下趨(qu)向(xiang)本(ben)設備(bei)陽極(正極、本(ben)設備(bei)采用(yong)負(fu)(fu)高(gao)壓(ya)制)和(he)陰極(負(fu)(fu)極) ， 釋放(fang)出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)子分別沉積在(zai)相應的(de)電(dian)(dian)(dian)(dian)(dian)(dian)極上，通(tong)過(guo)設備(bei)陰陽極振打(da)系(xi)統(tong)的(de)振打(da)，使沉積在(zai)陰陽電(dian)(dian)(dian)(dian)(dian)(dian)極上的(de)粉塵(chen)(chen)(chen)振落(luo)，進(jin)(jin)人(ren)(ren)集(ji)灰斗(dou) 通(tong)過(guo)排灰裝置放(fang)出(chu)，回收(shou)有物料(liao)，被)凈(jing)化的(de)氣(qi)(qi)體(ti)(ti)(ti)排入大(da)氣(qi)(qi)。

工作原理

靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)工(gong)作原理是利用高壓電(dian)(dian)(dian)(dian)(dian)(dian)場使煙(yan)氣(qi)發生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)離(li)，氣(qi)流(liu)中(zhong)的(de)(de)粉(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)(dian)場作用下與氣(qi)流(liu)分離(li)。負(fu)極(ji)由不同斷面形(xing)狀(zhuang)的(de)(de)金屬(shu)導線制成(cheng)，叫(jiao)放電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不同幾何形(xing)狀(zhuang)的(de)(de)金屬(shu)板制成(cheng)，叫(jiao)集(ji)(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)性(xing)能(neng)受粉(fen)塵(chen)(chen)(chen)性(xing)質、設(she)備構造和(he)煙(yan)氣(qi)流(liu)速(su)等三個因素的(de)(de)影響。粉(fen)塵(chen)(chen)(chen)的(de)(de)比電(dian)(dian)(dian)(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)指標，它(ta)對除(chu)塵(chen)(chen)(chen)效率(lv)有直(zhi)接的(de)(de)影響。比電(dian)(dian)(dian)(dian)(dian)(dian)阻過(guo)低，塵(chen)(chen)(chen)粒難以保持在集(ji)(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上，致使其重(zhong)返氣(qi)流(liu)。比電(dian)(dian)(dian)(dian)(dian)(dian)阻過(guo)高，到(dao)達集(ji)(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)(dian)荷不易放出(chu)，在塵(chen)(chen)(chen)層之間形(xing)成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)壓梯度(du)會產生(sheng)局部擊穿和(he)放電(dian)(dian)(dian)(dian)(dian)(dian)現象。這些情(qing)況都會造成(cheng)除(chu)塵(chen)(chen)(chen)效率(lv)下降。

電(dian)除塵(chen)器的基本原理是利(li)用電(dian)力捕(bu)集煙氣中的粉塵(chen)，主要(yao)包(bao)括以下四個相互有關(guan)的物(wu)理過程: (1) 氣體的電(dian)離。(2) 粉塵(chen)的荷電(dian)。(3) 荷電(dian)粉塵(chen)向電(dian)極移(yi)動。(4) 荷電(dian)粉塵(chen)的捕(bu)集。
